I want my phone to act as a ethernet capable wifi access point (WAN via ethernet).

When I use USB-OTG with an ethernet USB adapter attached to my Galaxy Nexus (non-rooted stock Jelly Bean) I get regular internet access just fine. Only thing I'm wondering about is the fact that 3G is shown in the status bar although mobile data connection is disabled. The connection goes over ethernet.

My Problem appears when I want to share this connection via wifi (hotspot). The hotspot is enabled and the other device (or whatever) is connected but it doesn´t get internet access...

Is this a known problem? Any ideas how to get this working?

Edit: It's not about 3G tethering, thats works fine. The problem is tethering while the phone is connected with the LAN over an RJ45-Ethernet adapter.

Some carriers disable 3G tethering in order to make more money, so if your carrier has installed software on your phone before hand to stop tethering the only way to make it work is to root your device and install an application that will allow you to do that.

The reason why it only connects is maybe because creating a hotspot to share files/resources over a LAN is allowed but to access the internet isn't. Right now, the FCC is forcing Verizon in particular to allow users to be able to share their phone's 3G internet.
